Potato and Soy Peptide Diets Modulate Lipid Metabolism in Rats.

The article discusses a study which investigated the physiological importance of potato peptides in rats fed on cholesterol-free diet. The diet contained 20% potato peptides was compared with two diets containing either 20% casein or 20% soy peptides. The study found high concentration of potato peptides and soy peptides on the fecal excretion of neutral and acidic sterols. The observed changes in the serum cholesterol levels in rats are associated with different mechanisms.
